Testing CPT invariance by using C-even neutral-meson-antimeson correlated states
Abstract
We consider the decays of a correlated neutral-meson-antimeson state with C-parity +1. We show that there is CPT noninvariance in the mixing of the neutral mesons if, for any two decay modes f and g, the decay rate has a component RA which is antisymmetric under the interchange of the decay times t1 and t2. In particular, one may cleanly extract the CPT-noninvariance parameter with the help of RA by using opposite-sign dilepton events.
